Evaluation and assessment are processes used to determine the significance, worth, or quality of educational programs, activities, and student progress. There are three main types of evaluation: preliminary evaluation occurs early to provide expectations, formative evaluation provides feedback to improve programs during development, and summative evaluation determines effectiveness at the end. Assessment involves documenting knowledge, skills, and attitudes, usually in measurable terms, and can be formative, summative, or evaluative to provide feedback to students and instructors or evaluate curricula. Assessment should be integrated within learning activities to build insight about learning.
